Quick selection diagram for Viking motors
The diagram below represents the torque and speed, for winch applications.
Oil viscosity in the motor case 40 cSt (187 SSU).
High torques
The Viking motor is a high-torque low speed motor,
which can be mounted directly on a winch drum or
to a shaft without intermediate gears. This presents
many practical benefits which appeal to the users of
the equipment.
High efficiency
The mechanical efficiency as well as the starting
efficiency is 97%. Because of the extremely low
moment of inertia the motor is virtually insensitive
to shock loads, and protects the driven equipment.
Viking is still the best tension control motor available.
Variable speed control
The Viking can drive and brake in both directions
with variable speed by smoothly controlling the flow
of oil in the circuit.
Severe environments
The Viking motor is designed to be highly resistant
to severe working conditions and environments. The
Viking has proven itself on board ships, in underwater
applications, in explosive and chemically corrosive
industrial environments, in extreme heat and freez-
ing cold.
Low speeds
Smooth, low speed performance from zero to rated
speed without the need of reduction gears and no
compromise on output torque.
Safety
For cranes and hoists Viking motors and brake as-
semblies are DNV approved. You don`t need to take
risks.

The Viking motors are radial piston type with rotating case. The case is supported on the stationary cylinder
block (5) by two main bearings. An even number of radially positioned pistons (3) work in cylinder bores in

The simplest way of performing displacement change over is by
connecting a spe cial valve, known as a 2-speed valve, direct to the connecting flange on the cy linder block.
The motor is designed so that pressure pulsations in the motor case are avoided. This has the advantage that
impurities are not sucked into the case.
the cy linder block, which also houses the inlet and
o ut let ports (A and C). Each piston is coupled by
a piston rod (2) to a cross head pin (6) upon which
four cam rollers (7) are mounted. The two inner cam
rollers press against the cam ring (8) while the two
outer rollers work with in their respective guide plates
(1). The cam ring is anchored to the rotating case.
The distributor (4) directs the input oil to the pistons
during their work strokes and re turns the exhausted
oil back to the tank. The distributor is coupled to the
rotating case via a safety coupling (9). The motor can
be connected to a driven machine via two mounting
surfaces on the rear end of the motor. The sym-
metrical design of the motor has made it possible to
construct it as a 2-speed motor. This means that two
different speeds are obtained for a given flow.

Data
Rated speed
1)
Rated speed is the highest allowed
speed for a charge pressure of 12 bar
(175 psi) above case pressure. When
a closed loop system is used, a mini-
mum of 15% of oil is to be exchanged
in the main loop.
Max speed
Maximum speed is the maximum al-
lowed speed. Special considerations
are necessary regarding charge pres-
sure, cooling and choice of hydraulic
system for speeds rated above.
Definitions
1)
Operating above rated conditions requires
engineering approval.
* Related to a required charge pressure of 12 bar (175 psi) for motors in braking mode. Special considerations regarding charge pressure,
cooling and choice of hydraulic system for speeds above rated.
** Theoretical value
*** The motors are designed according to DNV-rules. Test pressure 70 bar/1000 psi. Peak/transient pressure 70 bar/1000 psi maximum,
allowed to occur 10000 times.
Accepted conditions for standard
type of motor:
1. Oil viscosity 20 - 40 - 10000 cSt
(98 - 187 - 4650 SSU). See page 23.
2. Temperature -35°C to +70°C
(-31°F to +158°F).
3. Case pressure 0-3 bar (0-45 psi)
Pressure peaks and at standstill 8 bar
(116 psi)
4. Charge pressure (see diagram).
5. Volumetric losses (see diagram).

Brake assembly, type BA-43, BA-63 and BA-85
Accessories
Each brake is available in three versions depending on their brake direction, clockwise, counter clockwise
and double acting. The Viking band brakes are fatigue resistant for the maximum motor torque in each
motor series. The brake is intended to be used as a parking brake. For hanging loads in wet environments
we recommend the use of a protective cover over the band brake. The brake linings are of non-asbestos
material and have DNV type approval.

Parking lock unit
Parking lock unit for winch and industrial applications e.g. belt conveyor installations. The parking lock can
only be used were there is no demand for dynamic braking. In addition to the locking cylinder with bracket,
a ratchet-wheel (with data according to dimension drawing) must be installed on the outer mounting surface
of the hydraulic motor rear cover.

ON - The piston rod with
it´s head, is pressed
against the ratchet-wheel
due to spring-force.
OFF - The piston rod is
released from the ratchet-
wheel by means of oil
pressure.
Brake cylinder, type BCI-M
For brake assembly BA-43, BA-63 and BA-85. The brake
cylinder is the actuator for the Viking brakes. The band
brake, including brake cylinder, is the fail-safe type. This
means that the brake comes on due to spring force from
a strong spring inside the brake cylinder, if the pressure to
the cylinder is released. For good resistance to corrosion,
the piston-rod is chrome plated and made of stainless steel.

For applications in open and wet conditions we recommend a cover to be mounted over the bandbrake. This
is due to some brake efficiency losses in case of water on the lining and braking surface. The covers are
made of 4 mm (0,158 in) glass fibre reinforced plastic, and are to be used with brake bracket BB-46 / BB-85.
Harsh industrial environment
To protect the main seal when the motor is used in harsh environment, an extra V-ring can be mounted on
the 44- and 64-series motors. When using Hägglunds Drives bracket type BB-46, the guiding diameter is
already machined.

Flushing of motor case
The Viking motors have very high total efficiency, and they are now frequently used in applications with
high power. To avoid high temperature in the motor case the heat must be cooled away, because
Max power without flushing
Viking 44/64 120 kW (161 hp)

high temperature gives lower viscosity and that
gives reduction in basic rating life.
- For continuous duty in applications with an
ambient temperature of +20°C (68°F), the
motor case must be flushed when the output
power exceeds the values shown below.

Choice of hydraulic fluid
The Hägglunds Drives hydraulic motors are primarily designed to operate on conventional petroleum based
hydraulic oils. The hydraulic oil can be chosen in consultation with the oil supplier or your local sales office,
bearing the following requirements in mind:
General
The oil shall have FZG (90) fail stage minimum 11 described in IP 334 (DIN 51354). The oil must also contain
inhibitors to prevent oxidation, corrosion and foaming. The viscosity of mineral oil is highly dependent of the
temperature. The final choice of oil must depend on the operating temperature that can be expected or that
has been established in the system and not in the hydraulic tank. High temperatures in the system greatly
reduce the service life of oil and rubber seals, as well as resulting in low viscosity, which in turn provides
poor lubrication. Content of water shall be less than 0,1%. In Industrial applications with high demands for
service life, the content of water shall be less than 0,05%.
Recommended viscosity
At operating temperature: 40-150 cSt/187-720 SSU.
* Many hydraulic fluids with VI-improvers are subject to temper-
ary and permanent reductions of the viscosity.
** Low viscosity gives reduced basic rating life for the motors
and reduction of max allowed power.
Fire resistant fluid
The following fluids are tested for Hägglunds Drives motors (ISO/DP 6071).
*Vegetable fluids give good lubrication and small change of viscosity with different temperature.
Vegetable fluids must be controlled every 3 months and temperature shall be less than +45°C
(113°F) to give good service life for the fluid.
**Environmentally acceptable fluid give the same service life for the drives, as mineral oil.
Environmentally acceptable fluids
24
Choice of hydraulic fluid
Down rating of pressure, for motors used in systems
with fire resistant fluids, the maximum pressure for
motor given on data sheet must be multiplied with
following factors:
HFA-fluid not fit for use
HFB-fluid 0,7 x maximum pressure for motor
HFC-fluid 0,7 x maximum pressure for motor
HFD-fluid 0,9 x maximum pressure for motor
Down rating of basic rating life, for motors used in
systems with fire resistant fluids, the "expected basic
rated life" must be multiplied with following factors:
HFA-fluid not fit for use
HFB-fluid 0,26 x expected life with mineral oil
HFC-fluid 0,24 x expected life with mineral oil
HFD-fluid 0,80 x expected life with mineral oil
Down rating of pressure data and basic rating life
The oil in a hydraulic system must always be filtered and also new oil from your supplier has to be filtered
when adding it to the system. The grade of filtration in a hydraulic system is a question of service life v.s.
money spent on filtration.
In order to obtain stated service life it is important to follow our recommendations concerning contamina-
tion level.
When choosing the filter it is important to consider the amount of dirt particles that the filter can absorb and
still operate satisfactory. For that reason we recommend a filter with an indicator that gives a signal when
it is time to change the filter cartridge.
Filtering recommendations
Before start-up, check that the system is thoroughly cleaned.
1. In general the contamination level in our motors should not exceed ISO 4406 19/15 (NAS 10).
2. For heavy-duty applications the contamination level should not exceed ISO 4406 16/13 (NAS 7).
3. When filling the tank and motor case, we recommend the use of a filter with the grade of filtration β10=75.
Filtration
Explanation of "Grade of Filtration"
Grade of filtration β10=75 indicates the following:
β10 means the size of particle ≥10µm that will be removed by filtration.
=75 means the grade of filtration of above mentioned size of particle. The grade of filtration is defined as
number of particles in the oil before filtration in relation to number of particles in the oil after filtration.
Ex. Grade of filtration is β10=75.
Before the filtration the oil contains N number of particles ≥10µm and after passing the filter once the oil
contains number of particles ≥10µm.
This means that number of particles have been filtered (=98,6%).
